Hey, I have alot of the same problems with my car. I have a 93 prelude si 2.3 with 195,xxxk mikles. I let it go a long time (the oil leak(s)). Then the a/c stopped lowing cold. The oil leak suddenly turned into an oil gush on to the ground as i drive. After a month and a half of saving money with the lude parked i bought a bunch of parts online at rockauto. i bought all the seals except the head gasket crank rear main oil filter housing adapter valve cover trans cam seals etc... a water pump timing and balance belts and tensioners etc... i took it to the shop to get all installed for a labor charge of $380. they called me and told me to get a clutch kit and axles, and they would put em in for the same labor as quoted, so i did. i also put in new oil, gear oil antifreeze and filters. the car runs great now. but i still need the a/c fixed!! it was 102* yday
. anyway if you can aford to, then get all the seals and waterpump and timing stuff taken care of, to save it from going out in the near future. chances are if one seal fails the others will soon too. I'm still looking for a good deal on a a/c compressor if anyone knows where to get one. good luck with yer prelude too.
